Definitions

  • the present invention relates to the field of processes for metallizing parts, and in particular non-metallic supports. Different ways of performing metallization of a non-metallic support are known.
  • Electrolytic metallization processes in which a layer of chromium is deposited are also known.
  • One advantage of this type of process is the production of metallized parts having a metallic appearance. These parts are used in particular in the automotive field.
  • chromium and in particular hexavalent chromium, used in the context of metallization, has the disadvantage of being a toxic product for the environment.
  • Hexavalent chromium requires closed circuit wastewater treatment facilities to reduce its impact on the environment. It therefore represents a significant cost in the production of metallized parts.
  • Trivalent chromium is also a toxic chemical. Trivalent chromium poses the same problems as hexavalent chromium.
  • the document US 8,105,473 relates to a galvanic metal coating with an adjustable satin sheen in which a layer of Ni matte is deposited on a shiny surface and is coated with a layer of Ni sulfamate.

  • At least one layer of varnish is produced above the reinforcing layer.
  • At least one nickel layer is produced on the reinforcing layer and said at least one varnish layer is produced on the nickel layer.
  • the metal appearance is given by the presence of at least one layer of nickel which is placed on the reinforcement layer.
  • the metallized part obtained by implementing the process is devoid of chromium.
  • the varnish layer is deposited on the nickel layer in order to protect the nickel layer as well as the lower layers from the risk of corrosion and shocks from the environment in which the part is used.
  • the layer of varnish may comprise several layers of varnish obtained by successive deposits of varnish layers.
  • the layer of varnish covers the layer of nickel in order to improve the resistance of the part to shocks and to corrosion.

  • the ultraviolet drying step has an operating temperature lower than a temperature of a more conventional thermal drying whose temperature is above 120°C.
  • the non-metallic support is subjected to a lower temperature range in which the risk of degradation of said non-metallic support is reduced.
  • the layer of varnish is transparent or colored.

  • the non-metallic support has good fatigue resistance and has the advantage of being recyclable.
  • the adhesion layer is obtained by successively carrying out a chemical attack on the surface of the non-metallic support, an activation of said chemically attacked surface, and a deposition of a first layer of nickel or copper on the activated surface.
  • the surface first undergoes a chemical attack, for example by means of an acid in the case of a non-metallic support comprising acrylonitrile butadiene styrene, or of a base in the case of a support comprising a polyamide. A certain roughness of said surface is thus obtained.
  • the activation step is carried out by depositing a catalyst compatible with the material of said surface. In this way, a bonding layer is deposited on the activated surface in order to improve the adhesion of the reinforcing layer.
  • the reinforcing layer includes at least one layer of copper.
